Jeroen Koolhas and Dre Urhahn are two artist from Netherlands who started working together in 2005. In 2006, they started developing the idea of creating community-driven art interventions in Brazil. Their efforts yielded two murals which were painted in Vila Cruzeiro, Rio’s most notorious slum, in collaboration with local youth. After both murals were finished, they started their third stage of their project, ‘O Morro’.
